To (all whom it may concern Be it known that I, A anRT H. SAND- s'rnoM, a citizen of the United States, and a resident of Portland, county of 'Multnomah and State of Oregon, have inv e-nted anew and useful Fireplace Lining, ofwhich the 'tollowingi is a specification.

The present invention relates to improvements in fireplace liningsand has particular reference to a metal liningtor fireplaces composed of preferably four sections that may be easily assembled even by a layman and it will at the same time assist in the construction of the fireplace dueto the fact that it conforms to the outlines of a well constructed fireplace and thustorms a guide for the builder. A particular feature of the invention is that the sections are so constructed that the main sections are substantially adapted toybe used 1 01 any size of fireplace while auxiliary sections are provided which may be sold in the market in varying sizes so as to adjust the assembled lining to the size of fireplace desired. A further object of the invention is to incorporate in the lining a hinged cover plate which may serve as a damper and convenient means for adjusting the same. A further feature of the invention is the providing of vertical and horizontal beads on the inside of the lining for reinforcing purposes as well. as for the purpose of effecting amore tho-rough burning of the ases. Other objects and advantages of my device will appear as the specification proceeds.

The preferred form of my invention is shown in the accompanying drawing in which Figure 1 represents a vertical section through the device along line 1-1 of Figure 2, Figure 2 a front view of the device, Figure 3, a horizontal section through the same along line 3-3 of'Figure 2, Figure 4, an enlarged sectional detail view of a front edge of one of the side sections, Figure 5, an enlarged sectional detail view of a sliding engagement between the rear edge of a side section and the rear section, Figure 6 a sectional detail view illustrating the operating mechanism for the damper, Figure 7 a perspective detail view of a portion of the damper operating mechanism.

and Figure (8) a front view of a tube through which a chain operating the damper passes. While I have shown only the preferred form on the invention I wish to have it understood that various changes or modifications may; be made withinthe scope or the claims hereto attachedflwithout departing from the spirit of the invent-ion. My fireplace lining (1) is'preferably' made of four sections; including the le-ft hand section (2) the right hand. section a central section and a top 4 The two side sections (2 and3) are symmetrical in form and are curved to follow theoutlines or the fireplace. They coverthe sides of the fireplace and extend rearwardly to cover a large portion of the back of the fireplace. At thelatter end they terminate in grooves (7) adapted to slidably engage with the center piece (4). At, the front end they are provided with suitable flanges (8) adapted to engage theedgeofthe fireplace brick work. "These side sections are preferably-made oi standard size andtorender my lining available for different sized fireplaces I provide the central section (4) which may be made in different widths while conforming in length and in shape to the inner edges of the side sections. The lower portion of the three sections thus far described is preferably headed up to a height of about two feetin a manner shown in Figures 1 and 2; the beads (10) serving as reinforcing memhere for the metal plates and being adapted to arrest the upward motion of the inflammable gases and to thereby promote a more complete combustion of the same. For the purpose of firmly holding the three sections in place I provide in suitable places perforated lugs (9) on the back of the same which may be engaged by wires (11) worked into the brickwork.

The topsoi the three sections thus far described are shaped to form a slanting seat for the top plate (6) which latter is hingedly secured at the lower and forward ends of the supporting plates, semi-circular bearings (12) engaging corresponding seats (13). in the plates. Projections (1s on the front edges of the two side sections prevent the bearings from slipping off their seats. The top plate serves as a damper and its position may be adjusted by means of the ar rangement shown in detail in Figures (6, 7 and 8). A lug (16) rising from the central portion of the top plate is provided with a perforation (17) adapted to be engaged by a flat link chain 18 extending through a tube (19) embedded in the front wall (21) of the fireplace. To facilitate the handling of the chain a ring (22) is provided at its front end and a roller (23) between two ears (2st) at the rear end of the tube. The front end of the tube is threadedly engaged by a flange member (25) provided with a small slot (26) adapted to engage a link of the chain for holding the same and the top plate in any desired position. A hole (27) is provided in each side section to promote circulation of air behind the lining. Claims:

1. In a metal fireplace lining, a right and aleft side section each curved to also form a portion of the back of the fireplace with their edges spaced in confronting relation,

and a central back section connecting said edges in vertical grooved engagement, the

three sections being out on top to a single plane slanting downwardly toward the front of the fireplace, and a damper cover. thereover resting thereon and pivoted to the two front corners of the two side sections. i

8. In a metal fireplace lining, a right and a left side section each curved to also form a portion of the back of the fireplace with their edges spaced in confronting relation, and a central back section connecting said edges in vertical grooved engagement, the three sections being cut 011 top to a single plane slanting downwardly toward the front of the fireplace, a damper cover thereover resting thereon and pivoted to the two front corners of the two side sections, and means above said cover for opening it.

4. In a metal fireplace lining, a right and a left side section each curved to also form a portion of the back of the fireplace with their edges spaced in confronting relation,

and a central back section connecting said edges in vertical grooved engagement, said sections having a cellularly disposed interiorly ribbed surface.

5. In a metal fireplace lining, a right and left side section each curved to also form a portion of the back of the fireplace with their edges spaced in confronting relation, and a central back section connecting said edges in vertical grooved engagement, said sections having a plurality of vertical and cross ribs projecting from their inner surfaces forming a series of non-communicating heat deflecting pockets.
